This suggests that you are not running the latest version of calibre.
As for the custom fonts, if the CSS for an epub lists a font or type of font, i.e, font-family: Georgia, serif;, since the Georgia font is present, it will be used.
For font names, there have been many discussions over the years. The internal font name must match the font file name, the correct -Regular, -Italic, -BoldItalic or -Bold (-R, -I, -Z and -B also work) must be appended to the font-file name, etc.

I'll look into this tonight.
I'm running windows 10 which automatically updates all the time. i download calibre from the official site as the app brought me to the page automatically. I'm not at home, but it is the brand spanking new version as of a day or two ago when i did it. as for all the plug-ins, i went into the preferences and told it to check for all updated plugins and installed any it said weren't up to date.
i can verify the version numbers when i get home. I'm not an epub expert, but i am a technical supprt specialist very knowledgeable about all things computer, so I've done a fair bit of the expected troubleshooting before posting here. in fact many other sites shared similar epub vs kepub issues. kepub apparently simply adds its custom formatting via additionally span tags. but that additional formatting is supposedly what makes the typographical settings more fine tuneable.
I've even read that the kobo seamlessly initiates a completely different reader application for kepub vs epub. so the issues that i, and others, are seeing, seem less likely to simply be where i got the epub from. as i said I've obtained them from many sources. enough, in fact, that if the oasis worked perfectly with every book, and the kobo works with none, I'd argue the software is trash if it can't cope with common formatting quirks the oasis easily handles. but i don't want to jump to conclusions. i love my kobo with kepubs. wouldn't trade it for an oasis the scren is so nice and os more open. but i would simply like to figure this out so i could just use epubs or successfully convert and load kepubs when something like this happens.
